Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter

Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter (gas pressure type. ) The sensor part and the signal processing circuit are inside the junction box. It is used for high temperature, corrosive liquid, sewage, etc. The gas in the gas collecting cylinder is injected into the liquid Contact with the medium. The pressure is transmitted to the sensor through the air pipe. The direct contact between the sensor and the measured medium is avoided. It is suitable for occasions such as high temperature and strong corrosiveness. It effectively solves the problem of high temperature corrosive liquid and sewage level measurement. It is especially suitable for the measurement of high temperature, corrosive liquid and sewage.

Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter Working Principle

The Pressure Guided Submersible Level Transmitter selects the pressure transmitter as the pressure measurement component. The liquid level pressure signal is collected by the gas collecting cylinder and transmitted to the pressure transmitter to convert the pressure signal into the liquid level signal output.

The relationship between pressure transmitter and liquid level is: P=0.0098ρH+Pc

P pressure MPa;
ρ liquid density (g/cm3);
H liquid level depth (m);
Pc liquid surface pressure (normal pressure is 0)

Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter is a good choice for diesel testing.
Its biggest advantage is simple installation and low cost. Professional commissioning and installation, setup, etc. are not required. Just put the stainless steel probe into the tank and the solid gauge head.

In the petrochemical industry, large oil tanks require a large range of high-precision liquid level sensors to monitor oil level. At present, there are many methods for measuring oil tank liquid levels:

  • Servo level sensor
  • Radar level sensor
  • Hydrostatic liquid level transmitter
  • Magnetostrictive liquid level sensor

One of the more important factors to consider when choosing a submersible level meter in the wastewater treatment industry is chemical compatibility and material selection. From potable water to highly corrosive acids, submersible level
Meters are necessary to measure nearly countless liquid chemicals.

Long service life;
High-precision measurement is possible from water, oil to viscous paste;
A wide range of temperature compensation is not affected by the foaming, deposition, and electrical properties of the measured medium.

If you want to measure the liquid level of high temperature media, in addition to the available magnetic flap, the economical choice is the submersible high temperature Stainless Steel Level Sensor.

Since the medium is high temperature, the measurement method should avoid direct contact between the probe sensor and the medium. The probe sensor can only withstand a temperature of 60 degrees. For this reason, the submersible high temperature Stainless Steel Level Sensor is structurally designed to have the probe sensor above the medium and not in contact with the medium at all. . So no matter how high the medium temperature is, the submersible high temperature Stainless Steel Level Sensor can be used freely.

When installing, just find a hole larger than Φ37mm in the liquid level tank and put it directly. The submersible high temperature Stainless Steel Level Sensor is also equipped with a display for ease of use. Reasonable prices will make every customer satisfied.

More than just liquid level, monitor your tank volume more effectively!

Our liquid level sensors can output liquid level signals, such as 4-20mA signal, 0-10V signal, RS485 and so on.

However, the liquid level transmitter alone cannot calculate the liquid volume of tanks of different sizes. It’s too complicated. A separate recorder is required to calculate it.

Therefore, the digital display volume meter can collect, display and convert the liquid level of various regular and irregular tanks in the industrial field into the corresponding tank volume. It is suitable for monitoring, controlling and collecting various process parameters.
